An ink set for inkjet recording is provided that includes at least a colored liquid composition comprising at least a radically polymerizable compound, a photopolymerization initiator, and a colorant, and an undercoat liquid composition comprising at least a radically polymerizable compound and a photopolymerization initiator, the colored liquid composition comprising as the photopolymerization initiator at least one type of α-aminoacetophenone compound, and the undercoat liquid composition comprising as the photopolymerization initiator at least one type of compound selected from the group consisting of an acylphosphine oxide compound, an α-hydroxyacetophenone compound, and an oxime ester compound. There is also provided an inkjet recording method employing the ink set for inkjet recording, the method including a step of applying the undercoat liquid composition on top of a recording medium, a step of semi-curing the undercoat liquid composition, and a step of carrying out image formation by discharging the colored liquid composition on top of the semi-cured undercoat liquid composition.
本发明提供了一种用于喷墨记录的墨水组,该墨水组至少包括一种彩色液体组合物,该彩色液体组合物至少包含一种可径向聚合的化合物、一种光聚合引发剂和一种着色剂,以及一种底涂液体组合物,该底涂液体组合物至少包含一种可径向聚合的化合物和一种光聚合引发剂、着色液体组合物包含至少一种α-氨基苯乙酮化合物作为光聚合引发剂,底涂层液体组合物包含至少一种选自由酰基氧化膦化合物、α-羟基苯乙酮化合物和肟酯化合物组成的组的化合物作为光聚合引发剂。还提供了一种喷墨记录方法,该方法采用了用于喷墨记录的墨水组,该方法包括在记录介质上涂敷底层液体组合物的步骤、半固化底层液体组合物的步骤,以及通过在半固化底层液体组合物上排放有色液体组合物来形成图像的步骤。
